Stepper Motors Frame Sizes From NEMA 11 to 34

1 Stepper Motors Frame Sizes From NEMA 11 to 34. Wide Ra n of Moto ge r Sizes ! All models shown smaller than actual size. motor Wiring Parallel Connection (8-lead Motors ): OMEGA offers a robust line of 2-phase biploar step Motors ranging Drive A+ = Orange + Black/White in Frame size from NEMA 11 to NEMA 34. Most of our models are Drive A- = Black + Orange/White the high torque style, with holding torques up to Drive B+ = Red + Yellow/White 1845 oz-in. All Motors conform to industry-standard NEMA Drive B- = Yellow + Red/White mounting dimensions, and are offered with a range of well- Series Connection (8-lead Motors ): featured, compatible drives and indexers.

2 With the exception of Drive A+ = Orange our two smallest Motors (OMHT11-013, OM5014-842), all of our Drive A- = Black step Motors are optimized for microstepping: they can achieve a Drive B+ = Red stepping resolution of up to 51,200 steps/revolution Drive B- = Yellow ( per step) when operated by one of our microstepping Connect Orange/White to Black/White (not connected to drive). drives. In addition, these Motors can be operated in a closed-loop Connect Red/White to Yellow/White (not connected to drive). system for even more precise position control when fitted with one (4-lead Motors ): of our incremental encoders. Drive A+ = Red 8-lead Motors offer the flexibility of either series or parallel Drive A- = Blue connection.

3 The Motors should be series connected for best Drive B+ = Yellow torque at low speeds, and parallel connected for best torque at Drive B- = White higher speeds.
